Measurement of the hyperfine coupling constants and absolute energies of the $12s{}^2{S}_{1/2}$, $13s{}^2{S}_{1/2}$, and $11d{}^2{D}_J$ levels in atomic cesium

Abstract

We report measurements of the absolute energies of the hyperfine components of the $12s{}^2{S}_{1/2}$ and $13s{}^2{S}_{1/2}$ levels of atomic cesium, ${}^{133}$Cs. Using the frequency difference between these components, we determine the hyperfine coupling constants for these states, and report these values with a relative uncertainty of $\sim$0.06 %. We also examine the hyperfine structure of the $11d{}^2{D}_J$ ($J=3/2,5/2$) states, and resolve the sign ambiguity of the hyperfine coupling constants from previous measurements of these states. We also derive new, high precision values for the state energies of the $12s{}^2{S}_{1/2}$, $13s{}^2{S}_{1/2}$ and $11d{}^2{D}_J$ states of cesium.
